Since 1988, Hay-on-Wye has been the worthy venue for a literary festival which draws over 80,000 bibliophile visitors over 10 days at the end of May / beginning of June, in order to buy books, attend book launches and to see and hear big literary names from all over the world. High profile visitors to the Book Fair have included former US President Bill Clinton. http://wikitravel.org/en/Hay-on-Wye
